Abstract: A storage device includes; a non-volatile memory, and a storage controller including a processor, an accelerator and a memory storing a flash translation layer including a mapping table including mapping information between logical page numbers and physical page numbers. The processor may provide a command to the non-volatile memory and provide first mapping update information in a first mapping update size to the accelerator. Upon updating mapping information of the mapping table, the accelerator may update mapping information for logical page numbers and check continuity for the first mapping update information.
